Description
The Honeywell MSxx04F/MSxx09F Series Fire and Smoke Damper Actuators deliver 30 lb-in (MSxx04F) or 80 lb-in (MSxx09F) torque, designed to meet both UL-555 and UL-555S 350°F safety requirements for combined fire and smoke applications – the smaller-torque tier below the MSxx20F. Fast-acting spring return closes dampers in 15-20 seconds on power loss, holding rated torque even at reduced power. Die-cast aluminum housing allows flush mounting to the damper, with high-temperature Teflon lead wires. Stroke 95°±3°, mechanically limited, drives 0° to 95° and spring-returns automatically. Non-UL marked models also available. Jaideo Automation supplies Honeywell building automation products across India – contact us with your project requirements for a quotation.
